The Split Rock Lighthouse was constructed in 1910 in reaction to several shipwrecks resulting from a 1905 storm. Shipwrecks from a mighty 1905 November gale prompted this rugged landmark's construction. Today, the lighthouse has been restored to its 1920s appearance and, in conjunction with the visitor center and keeper's house, gives visitors a glimpse into the life at the lighthouse in the 1920s.

The lighthouse offers exhibits, guided tours, a historic house museum, and field trip programs. The website offers visitor information, a history of the lighthouse, a photo gallery, and information regarding upcoming events.

In 1837, Grover Cleveland was born in this house while his father, the Reverend Richard Falley Cleveland, was the minister to the First Presbyterian Church of Caldwell. Most of the first floor rooms portray the house as it was in 1837. Among the artifacts on display from Cleveland's early years are his cradle and original family portraits. The exhibit gallery features a striking display of artifacts that reflect the financial and political success Cleveland achieved during the last quarter of the 19th century. Here, the mud-slinging campaign of 1884, the public's intense interest in his wife and children, and America's political climate throughout his split terms of office are explored.

The site offers tours, exhibits, educational programs, and research library access.

After railroads made the region accessible in the late 19th century, coastal Maine became a fashionable destination for wealthy summer people. Many of the newcomers bought and restored the fine old houses built during the prosperous years following the American Revolution. In 1898, Mrs. Emily Tyson and her stepdaughter, Elise, purchased the c. 1785 Hamilton House, built on a site overlooking the Salmon Falls River. The Tysons flung themselves into a lifelong project to restore the house to its former glory. Influenced by literary imagery, including the writings of their neighbor and friend, Sarah Orne Jewett, they decorated with a mixture of elegant antiques, painted murals, and simple country furnishings to create their own romantic interpretation of America's colonial past.

The house offers tours and educational and recreational programs.

Historic Cherry Hill is a 1787 residence, occupied by the Van Rensselaer family until 1963. The site presents the changing culture, decorative arts, economic climate, and social classes of the 176 years in which the home was in use. The structure exists in its 1963 state in order to render social and architectural evolution visible to visitors. The Van Rensselaers were originally considered Hudson River manor lords, members of a group of wealthy local Dutch settlers. However, as early as the 1820s, the family began to face economic pressure which would increase with the formation of the millionaire class and the large numbers of immigrants entering the U.S. Collections include more than 20,000 artifacts—from the most mundane household items to rare examples of decorative arts styles—and 30,000 archival documents.

Cherry Hill offers period rooms; tours; interactive educational programs for students; and educational outreach programs for students. Reservations are required for groups of 10 or more. Listening assistance devices are available. The website offers two teaching units for purchase. Both won awards from the American Association for State and Local History.

Tours and on site educational programs are currently unavailable, as the site undergoes restoration. Outreach programming is still available.

The Justin Smith Morrill Homestead preserves the Greek Revival cottage of John Smith Morrill (1810-1898). During his life, Morrill worked as a blacksmith, merchant's clerk, Representative, and U.S. Senator. Unable to finish school himself, Morrill became the chief sponsor of the 1862 Land Grant Act. The act provided for a college in each state which would teach skills not previously available in the higher education system—practical science, agriculture, and engineering. These colleges also offered more traditional studies. Morrill's hobbies included architecture and landscape design.

The homestead offers period rooms, tours, gardens, and access to Morrill's library. Please call ahead to verify admission hours. Appointments are required for library access. The website offers suggested reading and a video virtual garden tour.
